Design and Implementation of Second-hand goods renting System Based On Ethereum Smart Contract

Ethereum blockchain is a revolutionary decentralized database technology on the Internet, with the characteristics of data tamperability, disintermediation, autonomy, traceability, point-to-point transaction, programmable and so on. Its emergence has an important impact on the development of many traditional industries. This paper analyzes the shortcomings of the traditional second-hand goods rental system and uses the blockchain technology to design the second-hand goods renting system based on ethereum smart contract. It introduces the background of blockchain and Ethereum smart contract, gives the overall framework of system design, and specifically describes the three parts of the system: blockchain module, smart contract module and the front end of DAPP, and the problems of combining blockchain and rental system are analyzed to provide a reference for better applications in the future.
